| 摘 要： | 根据部分稳定氧化锆陶瓷(PSZ)的增韧机制,减小陶瓷粉料ZrO_2颗粒的尺寸是提高陶瓷韧性及其它机械性能的关键,因此合成细微ZrO_2粉料的研究开展得十分活跃.韩利成等用液相沉淀法制备尺寸在微米级以下的氢氧化锆颗粒.村濑嘉夫等在H_2O_2存在下升温水解ZrOCl_2溶液,制备ZrO_2超细颗粒.从所发表的透射电子显微镜(TEM)照片看,他们所制得的颗粒形状和尺寸都不均一,而且粘连,恐难以满足烧制高韧性PSZ

| Abstract: | This paper describes the preparation of monodispersed sol of zirconium basic carbonate consisting of particles with diameter less than 0.6 μm by aging Zr(Ⅳ) solution at elevated temperature in the presence of urea and glycerol. The composition of the monodispersed particles has primarily been determined by the IR spectra and the weight-loss of the particles on calcination. The monodispersed particles of ZrO_2 were obtained by calcination of the monodispersed particles separated from the sol at 850 ℃ for 2 h. |
